Intel confirms switch to LGA 1700 socket for Alder Lake CPUs

It seems there’s nothing Intel loves more than launching new sockets. With LGA 1200 only recently released alongside the 10th-gen Comet Lake chips, more evidence has emerged that the 12th-gen Alder Lake processors will switch to a new, LGA 1700 socket.
Soon after the Core i9-10900K CPU was revealed back in April, we got confirmation that the new 400-series motherboards would also support the 11th-gen Rocket Lake CPUs, which are due to arrive next year.

In May, a Taiwanese company that provides voltage regulation test tools to Intel in the Asia-Pacific market suggested that the LGA 1200 socket will only be used for two generations of processors. It listed several future Intel CPUs, including the codename for Alder Lake-S with a description revealing it supports the LGA 1700 socket.

Now, a leaked Intel document from twitter user @momomo_us seemingly confirms it: those who want an Alder Lake CPU will need a new motherboard with an LGA 1700 socket. Alder Lake-S refers to the desktop chips, but it’s unclear what Alder Lake-P might be.

While the LGA 1200 socket brought few changes over its LGA 1150 predecessor, LGA 1700, which is expected to launch in early 2022, will reportedly be a lot different to what’s come before. In addition to the 500 extra pins, we’ve heard that the socket will be a rectangular shape (45mm × 37.5mm) rather than the usual square. We’ve also heard that Alder Lake will use a BIG.little design similar to Arm’s, combining eight high-powered cores with eight energy-efficient ones. It will also support DDR5 RAM and PCIe 4.0—later versions might support PCIe 5.0.

Alder Lake is expected to use the 10nm++ process node and will likely feature Intel’s Xe integrated graphics, which we recently saw running Battlefield V at 30fps on a laptop without a dedicated graphics card.
